installed 2nd video card, can't boot to Windows with both cards...

[snouter]

Perfectly fine i7 920 system as in my sig. I added a 4670 video card to the computer, and now I can't boot to Windows with both cards active.

Diamond 4890 1GB (1680x1050 monitor attached)
Diamond 4670 1GB (two 1280x1050 monitors attached)

I uninstalled the drivers, and reinstalled the drivers from the AMD website.

I get either a garbled signal and a blue screen complaining about the video driver, or it just kinds of cycles through trying to get synch.

Any ideas how to add a second video card?

Not interested in Crossfire, just trying to drive 3 monitors.

Thanks.

are you saying with your primary monitor hooked to your 4890 and nothing else, you can't boot with the 4670 installed?

what OS are you running?

Sys in sig worked fine for 2 weeks - vista 64

I added a 4670 and I can't boot with monitors connected to the 4670.

I moved the 4670 into the other PIC slot. No help.

I also unistalled the catalyst control center and driver and reinstalled.

I'm trying to drive the 1680x1050 as my main, center monitor from the 4890.

I'd like to drive two 1280x1024 monitors with the 4670.

I can run a 4670 and a 4890 in the same system right? (Both are Diamond cards)

I'm about to pull the 4890 out and try to just use the 4670 and make sure it works...

probably a good idea.

i was asking if with no monitors connected to the 4670 (but with it installed), you could still boot normally into windows with the 4890 display working fine. if so, does vista install the 4670?

Does plug-n-play handle IRQ assignments?

I think Plug-n-play is disabled in my BIOS.

I can boot with both video cardsinstalled and enabled, and a monitor attached to the 4890 and no monitors connected to the 4670.

Plug a monitor into the 4670 and signal is lost everywhere and the computer cycles trying to get synch. I can see some sort of Windows screen flash briefly, but it's black for the most part, or black with the little blue circle thing that has replaced the hourglass. Unplugg the monitor from the 4670 and the 4890 screen comes back with a message that the ATI driver hang was recovered.

I see weird artifacts in the BIOS, during post and when in BIOS.

I can't boot into Windows using the 4670. Did it once. Now I can only get into safe mode.

I'm about to speculate that the 4670 is not working correctly. Artifacts in BIOS don't seem right.

Pulled a 3850 from my home theater computer in there, and it worked perfectly.

It's all good, I had originally wanted to use the 3850 in this computer anyhow, since it's just driving the side monitors.

I'll return the 4670 and get something for the home theater - 2nd game machine...

thanks all...

CLIFF NOTES: adding a second card works as advertised if the cards are ok...

PS: 3 monitors rocks...
